This tidal sanctuary runs along the Mill Valley-Sausalito Pathway and the Charles F. McGlashan Pathway. More than 400 species of migratory birds rest here after their long flights, and if you pass through in the early morning or late evening, the sunrises and sunsets reflect beautifully on the surface of this 106-acre marsh.

There is a great view of the northern point of Alpine lake where a small channel feeds over to Bon Tempe Lake. This is a great place to drop a line, or just enjoy the aquatic views.
